CAT522

Configured Digitally Programmable Potentiometer (DPP™):

Programmable Voltage Applications

FEATURES

DESCRIPTION

Two 8-bit DPPs configured as programmable

The CAT522 is a dual, 8-bit digitally-programmable

potentiometer (DPP™) configured for programmable

voltage and DAC-like applications. Intended for final

calibration of products such as camcorders, fax

machines and cellular telephones on automated high

volume production lines, it is also well suited for self-

calibrating systems and for applications where

equipment which requires periodic adjustment is either

difficult to access or in a hazardous environment.

Independent reference inputs

Non-volatile NVRAM memory wiper storage

Output voltage range includes both supply rails

2 independently addressable buffered

output wipers

1 LSB accuracy, high resolution

Serial Microwire-like interface

The CAT522 offers two independently programmable

DPPs each having its own reference inputs and each

capable of rail to rail output swing. The wipers are

buffered by rail to rail opamps. Wiper settings, stored

in non-volatile NVRAM memory, are not lost when the

device is powered down and are automatically

reinstated when power is returned. Each wiper can

be dithered to test new output values without effecting

the stored settings and stored settings can be read

back without disturbing the DPP's output.

Single supply operation: 2.7V - 5.5V

APPLICATIONS

Automated product calibration.

The CAT522 is controlled with a simple 3-wire,

microwire-like serial interface. A Chip Select pin

allows several devices to share a common serial

interface. Communication back to the host controller is

via a single serial data line thanks to the CAT522 Tri-
